The mixture of peppermint oil (PO) with medium-chain triacylglycerol was emulsified in water and stabilized with
a food-grade biopolymer, modified starch, to form PO nanoemulsions. The effects of emulsifying conditions including
homogenization pressure, the number of processing cycles, and oil loading on the mean diameters and viscosities of
nanoemulsions were characterized by dynamic light scattering, optical microscopy, and rheological measurements. The
formulated PO nanoemulsions with mean diameters normally
